Nowadays, people, whether young or middle-aged, still have some old people who keep pace with the times. Most of them have WeChat. You can pick up your mobile phone and check your WeChat when you are free. You can put your own dialog box on his WeChat. As soon as he opens WeChat, he can see the chat with you, and also let others see or touch his mobile phone. You can know that this man is already taken, and other women have to let him go.

People who fall in love usually give each other a unique name to show their differences. Then, we can also put a private note on each other's mobile phone, so that our men will think of themselves when they see it. Also let others know that this man has a lover, and love is inseparable. So true love often has an intimate note, such as a little kiss, a wife and so on.

Because, we usually don't just look at friends. Sometimes, when interests or ideas come, we will also visit other people's circle of friends. So it is necessary to change the background of the other person's circle of friends to your photo or a group photo of the two of you. Everyone will pay more attention to their "friends circle". If it's not true love, it's hard to put pictures of two people on it. So at this time, women often not only swear sovereignty, but also vent a kind of love that is hard to give up.

You can give each other your own hair band. Of course, since it is for men, you can go to the store and buy a more neutral one. This headband is for him to wear on his wrist. Wearing it is to tell others that this man is taken. Ask other aliens to take the initiative to distance themselves from each other and stay away. Usually, girls give boys a rope to confirm their relationship, and the other means that it can not only swear sovereignty, but also prevent other friends of the opposite sex from approaching.
